Vorrichtung zur Sicherung des Betriebes von Schwerölmotoren, bei denen die Zündung des Brennstoff-Luft-Gemisches durch die Kompressionswärme eingeleitet wird.Device for securing the operation of heavy oil engines with which the ignition of the fuel-air mixture is introduced by the heat of compression.
Vorliegende Erfindung betrifft eine Sicherung für Motoren gegen Heißlaufen und verwendet zu diesem Zweck Schmelzsicherungen. Die Verwendung von Schmelzsicherungen ist bereits in verschiedenen Gebieten der Technik üblich, z. B. in elektrischen Leitungen, bei Dampfkesseln und auch bei Motoren, bei denen die Zündung des Brennstoffes durch elektrischen Strom bewirkt wird.The present invention relates to a fuse for engines against overheating and used fuses for this purpose. The use of fuses is already present in various areas of the world Technique usual, z. B. in electrical lines, in steam boilers and also in engines, in which the ignition of the fuel is effected by an electric current.
ίο Die vorliegende Erfindung besteht in der Anwendung einer Schmelzsicherung in Verbindung mit Rohölmotoren, bei denen bekanntlich die Zündung durch die Kompressionswärme eingeleitet wird, bei denen also eine Zündung mittels elektrischen Stromes nicht stattfindet.ίο The present invention consists in the Use of a fuse in connection with crude oil engines, in which it is known the ignition is initiated by the heat of compression, in which an ignition by means of an electric current not taking place.
Gemäß der Erfindung, welche in der Zeichnung in einem Ausführungsbeispiel in Anwendung auf einen Glühkopfmotor dargestellt ist, wird der Glühkopf mit einer Bohrung versehen (bei Dieselmotoren kann die Bohrung in der Zylinderwandung angebracht sein), welche das Zylinderinnere mit der Außenluft verbindet. In diese Bohrung wirdAccording to the invention, which is shown in the drawing in an exemplary embodiment is shown on a hot-bulb engine, the hot-bulb is provided with a hole (in the case of diesel engines, the hole be attached in the cylinder wall), which connects the inside of the cylinder with the outside air. In this hole is
as eine Schmelzsicherung eingesetzt von einer solchen Zusammensetzung, daß sie bei Heißlaufen des Motors bereits bei einer Temperatur schmilzt, bei welcher noch keine Beschädigung der laufenden Teile erfolgen kann. Läuft der Motor heiß z. B. infolge mangelhafter Wasserkühlung, so schmilzt die Sicherung, und der Kompressionsraum, des Motors tritt durch die Bohrung mit der Außenluft in Verbindung, infolgedessen kann die Kompression nicht mehr in dem Maße gesteigert werden, daß die Kompressionswärme zur Einleitung der Zündung genügt; die Zündung setzt aus, und der Motor bleibt stehen. In der Zeichnung bedeutet α den Glühkopf, der an den Zylinder b angesetzt ist; c ist die Glühplatte, e die Bohrung für die Brennstoffdüse, / der Kühlmantel für den Glühkopf. Gemäß der Erfindung ist der Zylinderkopf mit einer Bohrung g versehen, welche bei h ein Gewindestückt aufnimmt. In die Bohrung des Gewindestückes i ist die Schmelzsicherung k, d. h. ein Metallstück von leichter Schmelzfoarkeit, eingesetzt. I ist eine Kappe, die mit dem Gewindestück i verbunden ist. Diese Kappe/ überdeckt die Bohrung derart, daß die austretenden heißen Gase und flüssigen Metallteile der Sichenung abgelenkt werden, um zufällig an dieser Seite des Motors stehende Personen gegen Verbrennungen und Verletzungen zu schützen.As a fuse is used of such a composition that when the engine overheats it already melts at a temperature at which the running parts cannot be damaged. If the engine runs hot z. B. as a result of inadequate water cooling, the fuse melts, and the compression chamber, the engine comes through the hole in connection with the outside air, as a result, the compression can no longer be increased to the extent that the compression heat is sufficient to initiate the ignition; the ignition cuts out and the engine stops. In the drawing, α denotes the glow head which is attached to the cylinder b ; c is the glow plate, e is the hole for the fuel nozzle, / the cooling jacket for the glow head. According to the invention, the cylinder head is provided with a bore g which receives a threaded piece at h. In the bore of the threaded piece i , the fuse k, ie a metal piece of light fusible shape, is inserted. I is a cap that is connected to the threaded piece i . This cap / covers the bore in such a way that the escaping hot gases and liquid metal parts of the fuse are deflected in order to protect people who happen to be standing on this side of the engine against burns and injuries.
